I-80/Ashby Ave (SR-13) Interchange Improvements

The Alameda County Transportation Commission (Alameda CTC), in collaboration with the California Department of Transportation (Caltrans) and the cities of Berkeley and Emeryville, proposes to reconstruct the I-80/Ashby Avenue interchange to ease congestion, provide better interstate access, and connect pedestrians and cyclists to the San Francisco Bay Trail. 

The California Department of Transportation (Caltrans) is the state lead agency for the California Environmental Quality Act (CEQA) and the federal lead agency for the National Environmental Policy Act (NEPA). Alameda County Transportation Commission (Alameda CTC) is the project sponsor. Caltrans and Alameda CTC have prepared an Initial Study with Proposed Mitigated Negative Declaration (MND) / Environmental Assessment (EA) (“Draft Environmental Document”) for the project. Caltrans and Alameda CTC welcome the public’s comments on this Draft Environmental Document. The formal public comment period is from December 15, 2021 through January 31, 2022.
